. JAR TOP Filed Oct. l4, 1957 A TOR/V5! Patented Sept. 27, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to jar tops.

The principal object of this invention is the provision of a jar top that may be easily placed upon and removed from a jar. I

A further object of this invention is the provision of a jar top that may be clamped upon a Jar.

A further object of this invention is the provision of a jar top that may be securedby means of a clamp and a slidable wedge member cooperating therewith.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated'in the accompanying drawing, wherein:-

Figure 1 is a top plan view of the jar top in position upon the top of a jar.

Figure 2 is a side elevation, with parts broken away, of the jar top in position upon a jar.

Figure 3 is a cross section taken on line 3-3 of Figure 1.

By referring to the drawing it will be seen that there is provided a clamp I having down-turned portions 2 and 3, the extreme ends 4 of which are turned inwardly in order to fit underneath a peripheral flange 5 of a jar 6. It will be seen that the down-turned portion 3 is relatively shorter than the down-turned portion 2. By referring to Figure 1 it will be seen that there is positioned upon the clamp I a slidable wedge member comprising a flat pressure member I and a slightly curved pressure member 8. These pressure members I and 8 are formed of one piece of material and spaced apart by a slide member 9 formed by cut-out portions, between'the ends of the pressure members I and 8, turned upwardly and inwardly so as to fit loosely upon the clamp I.

By referring to Figure 3 it will be seen that the slightly curved pressure member 8 makes pressure contact at its extreme ends III with a jar top I I. By referring again to Figure 1, it will be seen that the jar top II is provided with raised portions l2 and I3, the portion I3 being slightly smaller than the portion I2. The raised portions I2 and I3 are spaced apart and have their inner edges I4 and I5 parallel to each other in order to form a slide-way for the flat pressure member I and to hold the clamp centrally upon the jar top II.

In placing the device upon the jar 6, the slide member 9 is slid outwardly so that the slightly '5 curved pressure member 8 comes in contact with the down-turned portion 2. The clamp I is then slid onto the jar top H, the outer edge I6 of the flat pressure member 1 sliding alongan edge II of the. raised portion I3. The raised portion I2 [101 being slightly larger than the raised portion I3, an extreme end I8 of the flat pressure member I will be stopped by coming in contact with the inner edge I4 of the raised portion I2. The clamping means is thenlcompleted by sliding the pressure members and connecting slide member intothe slide-way between the raised portions I2 and I3. A tightening of the top I3 takes place compressing the top firmly and evenly against a rubber ring I9 positioned between the upper edge 20 of the jar 6 and the lower surface of the jar top II.

By referring to Figure 1 it will be seen that the jar top is shown in a clamped position. The flat pressure member I presses downwardly uopn 5 the jar top II while the extreme outer ends II] of the curved pressure member 8 form compression points so that the jar is firmly held under' a three point compression. It is obvious that 30 in removing the clamp from the jar top it is necessary only to slide the pressure members I and 8 and connecting slide 9 back against the down-turned end 2, thereby releasing the pressure and allowing the clamp to be slid ofi.

What I claim is:-

In a jar top, a. clamp for said top, relatively short downwardly extending and inturned ends on said clamp adapted to fit underneath a peripheral flange of a jar, one down-turned portion 40 being relatively longer than the other, a curved pressure member and a flat pressure member together with a ,slide'member formed by cutout portions between the ends of the pressure members turned upwardly and inwardly to fit loosely upon the clamp, a pair of raised portions on said top, one larger than the other, said smaller raised portion adapted to allow the flat portion to slidepast it and the larger portion adapted to form a stop for therflat portion when 5 it reaches the center of the jar top where it can be slid between the raised portions, substantially as described.
